The history of the Vaillant Group dates back to 1874, when Johann Vaillant set up a master fitter's business. In 1894 Johann Vaillant patented a new "closed-system" gas-fired bathroom boiler. [3] This was the first device that made it possible to heat water hygienically, without contaminating it with combustion gases.
This committee put in the form work for the first edition of the ASME Boiler Code - Rules for the Construction of Stationary Boilers and for the Allowable Working Pressures, which was issued in 1914 and published in 1915. [5] The first edition of the Boiler and Pressure Vessel Code, known as the 1914 edition, was a single 114-page volume.
Boiler explosions are common in sinking ships once the hot boiler touches cold sea water, as the sudden cooling of the hot metal causes it to crack; for instance, when the SS Benlomond was torpedoed by a U-boat, the torpedoes and resulting boiler explosion caused the ship to go down in two minutes, leaving Poon Lim as the only survivor in a ...
Honeywell electronic thermostat in a store. Heating and cooling losses from a building (or any other container) become greater as the difference in temperature increases. A programmable thermostat allows reduction of these losses by allowing the temperature difference to be reduced at times when the reduced amount of heating or cooling would not be objectionable.
The furnace was placed in the space between the tube banks. Early boilers were manually coal fired, later oil fired. The boiler was enclosed in a sealed casing of steel, lined with firebricks. Brick-lined end walls to this casing housed the firedoors or oil burner quarls, but had no heating surface. The uptake flue from the boiler was in the ...
The weight problem was solved by adopting a new type of boiler, designated "Sural" (short for suralimenté [pressure-fired]); these boilers were much more compact than the type used in the Dunkerque class and the Richelieus had a wider beam (allowing three boilers side-by-side instead of just two), so the boiler rooms could be reduced from ...
The series was also adapted into a Michel Vaillant animated series. 65 episodes of 26 minutes were produced in 1990 in France by la Cinq. It was released in the U.S. in 1991-1992 as Heroes on Hot Wheels , produced by Jetlag Productions and the former Family Channel , sponsored by Mattel 's Hot Wheels franchise (hence the title) and distributed ...
